The funds intend to make regular monthly distributions to shareholders based on past and projected performance. Among other factors, the funds seek to establish a distribution rate that roughly corresponds to projections by the fund's manager, Nuveen Commodities Asset Management, of the total return that could reasonably be expected to be generated by the funds over an extended period of time. Investors should not draw any conclusions about a fund's past or future investment performance from its current distribution rate. As market conditions and portfolio performance may change, the rate of distributions on the shares and the funds' distribution policy could change.
